For numeracy, I again follow the national curriculum and use the main website (find link in 'resources') to plan lessons.
The planning structure for the year 2 numeracy curriculum is organised into 5 blocks. These 5 blocks are then split into 3 units each representing 2 or 3 weeks of teaching.
For maths we use a lot more workbooks and iPad apps to supplement learning. We also focus on memorising time tables almost every day.
